Definitions

  • the present invention relates to an operating head for machines for the processing of components made of wood or the like, according to the preamble of claim 1.
  • Such an operating head is known from the document US6164881A1 .
  • a machine of the type comprising an elongated base fitted with two longitudinal guiding members parallel to a substantially horizontal first direction; a plurality of cross members mounted between the longitudinal guiding members parallel to a substantially horizontal second direction transverse to the first direction; at least one supporting block mounted on each cross member to block the panels on a substantially horizontal supporting surface; and an overhead crane, which is mobile along the base in the first direction and extends over the base in the second direction.
  • the overhead crane supports an operating head, which performs machining of the panels, and is mobile along the overhead crane in the second direction.
  • the operating head comprises an electro-spindle, which is mobile in a third direction, substantially vertical and orthogonal to the supporting surface, and is equipped with an output shaft mounted to rotate around a rotation axis.
  • the output shaft defines a tool-holding spindle, on which a tool assembly provided with at least one tool for machining panels is fitted.
  • the operating head further comprises a suction hood, which extends around the tool assembly so as to suck shavings and/or swarf generated by the tool; and a pneumatic blowing device comprising, in turn, a plurality of blowing nozzles to clean the surface of the panels from shavings and/or swarf generated by the tool.
  • blowing nozzles are fixed inside the suction hood, the operating heads for known machines for processing wood components of the type described above have some drawbacks mainly due to the fact that the blowing nozzles have a relatively low effectiveness and efficiency.
  • an operating head is provided for machines for the processing of components made of wood or the like, as claimed in the appended claims.
  • a machine for the processing of components made of wood or the like defined, in this case, by substantially flat panels 2 made of wood or the like is globally indicated with 1.
  • the machine 1 comprises an elongated base 3, which extends in a horizontal direction 4, is substantially U-shaped, and has two lateral longitudinal guiding members 5 parallel to the direction 4.
  • the head 12 also comprises a pneumatic blowing device 20 so as to feed a flow of pressurized air through a cutting channel 21 made by the tool assembly 17 in the panel 2 to remove shavings and/or swarf generated by the tool assembly 17.
  • the device 20 comprises a coupling plate 22 fixed to the sleeve 19, a support bracket 23 rotatingly coupled to the plate 22 so as to rotate, according to the invention with respect to the plate 22, around a rotation axis 24 transversal to the axis 16, and, in this case, two blowing nozzles 25 fixed to said bracket 23.
  • the head 12 is further provided with a suction hood 26, which extends around the tool assembly 17 and the sleeve 19, is connected with a pneumatic suction device, known and not illustrated, and has an input mouth 27.
  • the blowing device 20 is mounted between the tool assembly 17 and a deflector , which is mounted within a perimeter of the mouth 27, is oriented so as to direct in the hood 26 shavings and/or swarf not intercepted by the nozzles 25, and is slidingly coupled to the bracket 23 to selectively vary its distance from the panel 2.
  • Moving the sleeve 19 around the axis 16 allows the nozzles 25 and the deflector 28 to always remain aligned with the tool assembly 17 in one direction of advancement of the tool assembly 17 along the channel 21, the nozzles 25 to correctly feed the flow of pressurized air inside, and through, the channel 21, and the deflector 28 to correctly deflect the shavings and/or swarf inside the hood 26.
  • each nozzle 25 comprises a flexible segment to selectively orient the blowing nozzle 25 in space.
  • the electro-spindle 14 is mounted to rotate, with respect to the head 12, around a further rotation axis parallel to the axis 16, in particular coinciding with said axis 16;
  • the assembly defined by the pneumatic blowing device 20 and the deflector 28 is angularly integral with the electro-spindle 14 so as to rotate around said further rotation axis.
